Removed the IfaceMgr.detectIfaces_linux test as it is covered in the
IfaceMgr.detectIfaces test already.

The original version of this test incorrectly matched the names of the
interfaces detected by the IfaceMgr and those detected by the unit test.
As a result, the interfaces with similar names (e.g. virbr0 and virbr0-nic)
where compared for the equality of indexes, addresses and flags.

It was failing on a few different systems.
Okay to disable via jabber.
The ticket is #3510.

This message is only output when a receive operation is cancelled,
so the parameter was always the text "operation aborted" - which
gives no new information.
